Fingal's Cave, Staffa. Walking on black stone.

The author feels that perhaps some explanation is due to the reader for the rather unusual employment of the word "Sensuality" which serves as the title of this work. The advantage given to the author by the use of this particular expression is that it enables him to proceed from rock-bottom upwards as far as he likes. A more refined title would have cut him off, in his method of developing his idea, from the physical roots of existence; for while it is easy to indicate the overtones and undertones of Sensuality it would be hard to bring a gentle, vague word, like the word "sensuousness" down to the bare, stark, stoically-stripped Life-Sensation which is the subject of this book.
